Transition metal dichalcogenides (TMDs) have provided a fundamental stage to study light–matter interactions and optical applications at the atomic scale due their ultrathin thickness appropriate band gap in visible region. Here, we report strong nonlinear effects, including second-harmonic generation (SHG) third-harmonic (THG) spiral WS2 structures. SHG intensity quadratically increases with layer numbers, other than diminishing oscillation of 2H stacking TMDs. The contrary behavior is...
Abstract 2D vertical van der Waals (vdW) heterostructures with atomically sharp interfaces have attracted tremendous interest in photonic and optoelectronic applications. Band alignment engineering provides a perfect platform for tailoring interfacial charge transfer behaviors, from which desired optical features can be realized. Here, by developing two‐step chemical vapor deposition strategy, direct growth of monolayer PbI 2 on transition metal dichalcogenides (TMDCs) (WS , WSe or alloying...
Abstract The rational control of the nucleation and growth kinetics to enable 2D vertical heterostructure remains a great challenge. Here, an in‐depth study is provided toward understanding mechanism transition metal dichalcogenides (TMDCs) heterostructures in terms kinetics, where active clusters with high diffusion barrier will induce on top TMDC templates realize heterostructures. Based this mechanism, experiment, through metal/chalcogenide ratio vapor precursors, effective manipulation...
Abstract For decreasing the global cost of corrosion, it is essential to understand intricate mechanisms corrosion and enhance resistance materials. However, ambiguity surrounding dominant mechanism calcium‐magnesium aluminosilicate (CMAS) molten salt in extreme environments hinders mix‐and‐matching key rare earth elements for increasing monosilicates against CMAS. Herein, an approach based on correlated electron microscopy techniques combined with density functional theory calculations...
Abstract: After oral administration in rodents, triptolide (TP), a diterpenoid triepoxide compound, active as anti-inflammatory, immunosuppressive, anti-fertility, anti-cystogenesis, and anticancer agent, is rapidly absorbed into the blood circulation (from 5.0 to 19.5 minutes after dosing, depending on rodent species) followed by short elimination half-life about 20 less than 1 hour). Such significant rapid fluctuations of TP plasma likely contribute its toxicity, which characterized injury...
Thermodynamic destabilization of magnesium hydride is a difficult task that has challenged researchers metal hydrides for decades. In this work, solid solution alloys were exploited as way to destabilize thermodynamically. Various elements alloyed with form solutions, including: indium (In), aluminum (Al), gallium (Ga), and zinc (Zn). properties the reactions between hydrogen investigated. Equilibrium pressures determined by pressure–composition–isothermal (PCI) measurements, showing all...
Triptolide (TP) often causes adverse reactions in the gastrointestinal tract when it is administered orally. This study aimed to prepare and optimize triptolide-loaded solid lipid nanoparticles (TP-SLN) with reduced gastric irritation. The microemulsion technique was used formulate TP-SLN employing a five-level central composite design (CCD) that developed for exploring optimum levels of three independent variables on particle size, encapsulation efficiency (EE) drug loading (DL). Quadratic...
van der Waals multilayer heterostructures have drawn increasing attention due to the potential for achieving high-performance photonic and optoelectronic devices. However, carrier interlayer transportation behavior in structures, which is essential determining device performance, remains unrevealed. Here, we report a general strategy studying manipulating multilayers by constructing type-I heterostructures, with desired narrower bandgap monolayer acting as extraction layer. For comprised of...
The wavelength-tunable interlayer exciton (IE) from layered semiconductor materials has not been achieved. van der Waals heterobilayers constructed using single-layer transition metal dichalcogenides can produce continuously changed band gaps, which is a feasible approach to achieve tunable IEs. In this work, we design series of heterostructures composed WSe2 layer with fixed gap and another WS2(1-x)Se2x alloy gaps. existence IEs gaps in these verified by steady-state photoluminescence...
Recombination dynamics during photoluminescence (PL) in two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) are complicated and can be easily affected by the surroundings because of their atomically thin structures. Herein, we studied excitation power temperature dependence recombination on chemical vapor deposition-grown monolayer WS2via a combination Raman, PL, time-resolved PL spectroscopies. We found red shift parabolic intensity increase emission WS2 with...

We present a high-pressure NMR study of the overdoped iron pnictide superconductor ${\mathrm{NaFe}}_{0.94}{\mathrm{Co}}_{0.06}\mathrm{As}$. The low-energy antiferromagnetic spin fluctuations in normal state, manifest as Curie-Weiss upturn spin-lattice relaxation rate $1/^{75}T_{1}T$, first increase strongly with pressure but fall again at $P>{P}_{\mathrm{opt}}=2.2\text{ }\text{ }\mathrm{GPa}$. Neither long-ranged magnetic order nor structural phase transition is encountered up to 2.5 GPa....
